There are a few things I don’t quite get.
I don’t see how there’s much benefit in this. I play green because it (or at least my current inventory) is the fastest option, and I must not be the only one with this (or a similar) view, because the majority of my opponents are using green as well, so the majority of the time, won’t I be slowing myself as much as my opponent, since my opponent’s color is also my own?
These new mechanics add an incredibly interesting layer to the game - you can build decks to counter specific other decks with these things in a lot of interesting ways.
How is this feasible? I get it for story mode, because that’s how I’ve been getting the crystal rewards (tweaking my decks for a specific purpose), but it is a tedious and incredibly time-consuming process. The deck building interface is incredibly annoying, so to me, it’s not really an option to tout as an exciting opportunity. Even less so, since building your deck specifically to counter another deck can’t even be done in PVP; it’s not like you can know what deck you’re going to be up against, and it’s one and done, so you can’t even sideboard like with regular Magic.
Or am I completely misconstruing your intention?
On a side note, it would be great if we could save multiple decks so we don’t have to slog through the editor when we want to counter a specific other deck.
We wanted to add a new Support for Blue that would reward players for playing tactically with the board and work towards making Match-5s more often
Until last week, I didn’t think it was possible to actually work towards making Match-5s; it always seemed to be nothing but chance. I figured out a way to make them more frequent, but it’s still more luck than planning. Will there be any changes upcoming that make them easier to come by? And are there any tips you would be willing to give in order to more frequently take advantage of Match-5s?
The general feeling I’m getting from what you’ve so far said of BFZ is that there may be some new, fun, and interesting ways to play in story mode, but in PVP, it may be lacking. That’s not a criticism of the impending release, mind you (I wrote with the utmost respect), because, as you’ve said, there’s more to be revealed, and I just may not have a clear picture. Or I may just be stupid. Or something else, maybe.
I’m assuming that you guys have been play testing with the new mechanics; do they work as intended in both PVP and story mode? Are my fears ill-founded?
Also, will there be any UI or other general updates? I believe I read that duplicate cards can be cashed in for runes, and that creature types will be visible, but (if this isn’t stepping on the toes of planned pre-release news) will there be any others? Liiiiike an inclusion of a graveyard? Because that would be super useful 
Also also, so you don’t think I’m just some Negative Nancy or Doubting Dorothea, I wanna say that I love the game in general, and I’m really looking forward to BFZ, even if I don’t yet understand how it will fit into my playstyle. Thanks for doing the things you do!
